Abstract: The invention relates to a device for producing hollow bodies from thermoplastic material in which web- or strip-type preforms of plasticised plastics material are shaped in a multi-part tool which forms a mould nest, with two outer moulds and a central mould which perform opening and closing movements with respect to one another. The central mould is provided with at least one device for receiving and manipulating components to be fastened in the interior of the hollow body by means of a material and/or form-fitting joint. Prior to the fastening of the components to the inner wall of the hollow body to be produced, the components are heated by means of a radiant heating device. The radiant heating device is advantageously integrated in the central mould of the tool.

Abstract: Regulating the rotational speed of the driven rotor of a viscosity coupling to a predetermined speed with a control circuit having a switching mechanism. When the speed drops below certain values, the speed is adjusted back to the predetermined value.

Abstract: A control system for a fan of a cooling system of an internal combustion engine of a motor vehicle having a viscous coupling (fan clutch) driving the fan and a control unit (PID governor) to which the setpoint temperature and the measured actual temperature of the cooling system (coolant temperature) are fed. The control unit (PID governor) is connected downstream to a limiter, which holds the ratio of output speed to input speed below a specifiable limit (x % of input speed). An overheat protection logic disables the limiter when the actual coolant temperature exceeds a specifiable critical temperature that is higher than the setpoint temperature of the control unit (PID governor).

Abstract: A method and materials are disclosed wherein a layer of a softer thermoplastic material comprising (i) a thermoplastic polyurethane or (ii) a thermoplastic elastomer alloy including a styrenic thermoplastic elastomer and a thermoplastic polyurethane can be attached to a substrate comprising a harder thermoplastic alloy including a polyester and a polycarbonate. In one form, the method and materials are used to form a modular chain link for use in constructing a modular conveyor chain. The modular chain link includes a main body comprising the thermoplastic alloy including a polyester and a polycarbonate, and a softer layer of the thermoplastic material comprising (i) a thermoplastic polyurethane or (ii) a thermoplastic elastomer alloy including a styrenic thermoplastic elastomer and a thermoplastic polyurethane disposed on at least a portion of the main body.

Abstract: A fluid friction clutch, in particular for the fan of the radiator of an internal combustion engine, is described. A valve element (22) controlling the clutch is operated via a solenoid control by means of a piston rod (24) which is guided coaxially in the drive shaft (12) of the clutch. The piston rod (24) includes an anchor (28), which is guided in the drive shaft (12). An actuator coil (34) is received in the magnet body (32), which is seated rotatably upon the drive shaft (12). The drive shaft (12) guiding the anchor (28) is provided with a non-magnetic separation gap (38).

Abstract: The present invention provides a method for predicting the risk of occurrence of cancer. It also predicts the presence of BRCA mutations which in turn predicts the risk of developing breast cancer in women. Further, it assesses a cancer patient's level of sensitivity to chemotherapy.

Abstract: A fluid coupling device in which the input coupling member (11) includes a plate-like member (29) defining a first inlet port (63), and a second inlet port (67) disposed radially outward of the first inlet port. The device includes a valve member (43) having a disengaged position (FIG. 4) blocking flow through both inlet ports. As the valve member (43) moves from the disengaged position toward a first operating position (FIG. 5) the first inlet port (63) is uncovered, while the second inlet port (67) remains covered. Continued movement of the valve member results in progressive uncovering of the second inlet port (67). Finally, there is a third inlet port (73), radially outward from the second inlet port (67), and further movement of the valve member (43) eventually uncovers the third inlet port.
